Abstract

An assembly kit has a hollow structural element having at least one groove inwardly of a face thereof and open to the hollow of this structural element, and a recess communicating with the groove and open at the face of this structural element. Another structural element is positionable on the first-mentioned hollow structural element and has another groove which is smaller than the groove of the hollow structural element. A connecting element is provided, which has one portion insertable in the one groove of the hollow structural element, and another portion insertable in the other groove of the other structural element so as to connect the above structural elements with one another. The connecting element has also a third portion insertable in the recess of the hollow structural element so as to prevent the connecting element from moving inwardly of the hollow of the hollow structural element.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a connecting element for interconnecting building blocks provided with chamfered grooves and building blocks having cavities, which are provided with slots extending to chamfer into the interior space of the building block and out of the connecting means of the aforementioned building blocks, with correspondingly larger connecting means.

· Connecting parts for mutual coupling of building blocks of the same kind · · · and with bevelled grooves are known. Those ^·; the connecting parts are provided with two. · The same; in the longitudinal direction into one piece by means of interconnected connecting strips, which can be inserted into the bevelled grooves of successive building blocks.

For handling reasons, it has proved to be expedient to provide construction kits for adapting to different manual skills of children, in addition to small ones, and consequently multi-faceted building blocks with fine fasteners, also larger building blocks with fasteners of larger dimensions. With increasing age the skill of the child increases, so it is necessary to replace the kit for more complex. A kit with larger building blocks and coarser fasteners becomes worthless soon for the child.

The object of the invention was to provide a connecting piece which allows the combination and the assembly of the two modular systems.

This problem has been solved according to the invention in that the connecting piece is provided with two connecting strips interconnected in the longitudinal direction, one of which is inserted into the tapered grooves of the solid building block and the other one of the slots. a hollow building block having a chamfer, wherein a flange is provided between the two connecting rails to form a rigid connection of the hollow building block. *

The slot serving as the connecting means of the hollow building block, apart from the side walls, is not limited in the interior of the building block. As a result, the connecting strips introduced into the slot could engage in the interior of the building block, in the absence of a support strip support on the surface of the building block. Such a support has proven expedient for a connecting bar fixed to the building block. Such abutment also occurs when this coupling of two hollow building blocks with equal-sized slots is carried out by means of a connecting piece which is formed by two equally sized holes. Convenient connecting strips are connected to each other in the longitudinal direction. Due to the narrowing of the slot towards the surface, a stop edge is provided here, suitable for the reinforcement of the connecting bar protruding from the surface of the building block. However, these assumptions are out of the question if the connecting bar protruding from the hollow building block is adapted to a substantially smaller chamfered slot of the building block of another kit. Through amplification. In this connection strip, the wide, unrestricted slot of the hollow building block falls through the inside of the building block. The use of the flange according to the invention between the two different connecting strips avoids this drawback. will prevent. However, the flange impinging on the surface of the building block would change the dividing ratio existing between the small building block r by the larger hollow building block, which would greatly affect the assembly.

In order to avoid this, according to the invention, the hollow building block is provided with a depression formed parallel to the slot and intended to receive the flange.

By this arrangement, the surfaces of the building blocks are brought directly into each other, thereby preventing incorrect assembly of the building blocks.

According to a further embodiment of the invention, the connecting rails of the connecting part may be in the form of bolts and provided with a notch formed in the longitudinal direction of the connecting rails. The notch confers flexibility to the tie bars, which results in good sliding and fastening properties of the tie bars in the grooves at larger clearances.

An exemplary embodiment of the invention is shown in the drawing. v. axonometric view.

The hollow building block 1 is provided on one surface with slots 2 extending into the inside of the building block, suitable for receiving bevelled pins or bars of other building blocks. To accommodate the pins, the slots 2 in the space of the side walls 3 of the building block are selected at right angles while continuing the slot expansion. To connect the hollow building block 1 with the solid building block 4,. which, when compared with the hollow building block connecting means, has smaller grooves 5, the connecting piece 6 is inserted into the slot 2 of the hollow building block 1, which is provided with two connecting bars 7a, 7b connected to each other in the longitudinal direction and slots of connecting building blocks. A flange 8 is provided between the two connecting strips 7a, 7b to support the insertion of the coupling part, which is supported by the surface of the building block. The flange 8, inclined towards the reinforced cross-section connecting bar, is mounted in a parallel chamfer 9 formed in the surface of the building block 1, so that when the solid building block 4 is inserted, its front surface abuts immediately on the surface of the hollow building block 1.

The connecting strip 7a of the connecting piece 6 with a larger cross-section is formed in the form of a tube, the diameter of the opening 10 corresponding to the diameter of the tubular groove 5 of the smaller building block 4. This also allows the pins 11 to be inserted into the tubular groove of this building block.

In order to limit the clearances of the fasteners, the fasteners 7a, 7b are made resilient by means of a notch 12 formed in the longitudinal direction of the fasteners 7a, 7b.
